BOOK-COVER RUBBING AND CLEANING MACHINE.

assess.

Application filed September 3, 1910.

To all whom it may concern:

Be it known that we, ANTHONY L. Dnnx LER and WILLIAM H. DITTMAR, bothcitizens of the United States of America, and residents of Jersey City,in the county of Hudson and State of New Jersey, have jointly invented anew and useful Book-Cover Rubbing and Cleaning Machine, of which thefollowing is a specification.

This invention relates to a novel machine for rubbing and cleaning bookcovers particularly devised for the purpose of removing the excess ofgold leaf, silver leaf, aluminum leaf and metal leaf in general from theback and sides of the book cover when same are ornamented by print andembellishing designs.

Heretofore when the title of the book, the authors' name or the like wasapplied to the back of the book cover or when the sides were embellishedby beautiful designs, the letters and designs were first usuallyproduced thereon by printing them without any color or gold leaf forinstance, so that there were merely impressions in the cover. Then thegold leaf was applied largely in excess and that excess was generallyremoved by hand. This was a rather tedious, painstaking and time takingoperation involving considerable expense.

The present invention has for its purpose to produce a book coverrubbing and cleaning machine which removes the excess of gold leafquickly and effectively without injuring or defacing the desired goldenprint or ornamental designs. For this purpose we have constructed amachine comprising an automatic feeding device, a reciprocal movementwith soft rubber attachment at the bottom of same or a suitable brush soconstructed that the soft rubber or brush passes over the book cover andremoves the excessive gold leaf. Means are provided for shifting thebook cover into the machine and means for securing the latter in a fixedposition. There are further means to deliver the cleaned book coversinto a suitable box or basket, and means to recover the excessive metalleaf, all as will be fully described hereinafter with reference to theaccompanying drawings in which:

improvements. Fig. 2 is a side elevation of same. Fig. 3 is alongitudinal vertical section through the machine. Fig. 4 illustratesthe machine in front View, and Fig. 5 is a vertical sectional detailview of the driving mechanism shown in Fig. 3.

Similar characters of reference denote like parts in all the figures.

In the drawings a represents substantial frame work with a supportingplate Z) extending laterally. The plate I) is centrally cut out as shownin Figs. 1, 2 and 3 for purposes to be mentioned later on. Two guideplates 0 are adjustably mounted on the plate Z) one each near its sideend portions. Below these guide plates there are slots 5 in the plate 5to allow of adjusting said guide plates sidewise so as to convenientlysupport book covers of various sizes. A third plate (Z is stationarilyfixed to the plate 5 in the center of same between the guide plates 0.On the plate d rests the curved back of the book cover during theoperation of the machine while the sides of the cover rest on the guideplates 0.

On the supporting plate Z) there are bearings c to support the rollersf. These rollers may slide up and down in the bearings to allow of theinsertion of book covers of various thicknesses. Underneath the rollers7 there are rollers g driven by a chain it from the main shaft 2'. Abevel gear on the main shaft c meshes with a bevel gear j mounted on astud j which is in a bearing j on the table plate al On the shaft of thebevel gear j there is an eccentric to which a link 70 is connected. Atthe end of the link 70 there is a lever arm Z whose other end carries avertical shaft Z in a bearing m. On the top end portion of the shaft Z along horizontal arm a is provided. In order to substantially support thestud Z and the lever arm n a bearing m supported on the table plate ais.provided. The stud Z passes movably through the bearing m. At theother end of the lever arm a there is attached a divided support orholder 11 extending downwardly and carrying the brush or soft rubber 0which passes over the book cover during the operation of the machine forthe purpose of removing the excessive gold leaf or the like.

On the plate I) near its outer ends there are open boxes .9 for thepurpose of receiving the gold dust which has been removed by the softrubber or brush 0. The gold dust is drawn out of these boxes in theusual way by suction through pipes p which connect with a suction fan 9which in turn is driven by sprocket wheels 1 and a chain T whichsprockets 1" are connected to the main shaft by bevel gears W. In thisway the collected excessive gold leaf may be easily recovered.

The front roller g is divided into sections 9 as shown in Fig. 4 toallow of space for the guide plates which, by their adjustment, renderit possible to insert book covers of various widths. The rollermechanism draws in the book cover and the soft rubber or brush on thelever arm a cleans same. The book cover then falls through the openingin the supporting plate 5, above mentioned, into a basket or the like.The rollers f are in frictional contact with the rollers 9 when no bookcover is between them. Vhen a book cover is inserted between saidrollers it will be drawn in by the action of the rollers g which arepower driven and the rollers f then rotate by reason of being in contactwith the moving book cover. The main shaft 2' is rotated by means of apower pulley t mounted on said main shaft. The lever 91 which carriesthe soft rubber or brush 0 likewise is driven from the main shaft z asabove described. By virtue of the eccentric is the lever 12 performs anoscillating movement and the soft rubber or brush passes over the bookcover to and fro whereby a perfect cleaning of same is effected. Theexhaust fan 9 for recovering the excess of gold leaf also is driven fromthe main shaft by the bevel gears r and sprockets r connected by thechain r Thus the feed rollers, the reciprocating lever with cleaningdevices attached thereto, and the exhaust fan for recovering the excessof gold leaf are all. driven from one main shaft and power pulley andall that is required is to feed the book covers into the machine andremove the filled baskets into which the cleaned covers fallautomatically. The machine therefore saves a great deal of wages andcleans the book covers more uniformly than they can be cleaned by hand.By the simplicity of its construction the machine may be operated by anyunskilled person but produces uniform and neat work.
